WordPress Blogs Update

So I’ve replaced the old WordPress Multiuser setup (WPMU) with WordPress 3. I have a slight feeling that old WPMU unpatched (and seemingly unpatchable after many attempts) was the reason the last server got hacked, so I’ve moved the active blogs and shut the old system down. Blog URLs should all be same. Content should be mainly imported. Passwords might be slightly different if I didn’t know what the old one was.
